Description

Technical Field

[0001] This application belongs to the technical field of zippers, clothing, and flexible bags, and specifically relates to a zipper pull and an article with zipper teeth. Background Technology

[0002] The zipper pull in the related technology includes a zipper pull body and a pull tab. The pull tab is rotatably connected to the zipper pull body, so that the pull tab can rotate 180° relative to the zipper pull body, so as to realize bidirectional pulling of the zipper pull by changing the position of the pull tab relative to the zipper pull.

[0003] When the zipper needs to be closed, the pull tab rotates to the front of the zipper head, and the user squeezes the pull tab with their fingers to pull the zipper head. However, when the user's fingers are sweaty or the zipper head is obstructed, the pull tab may slip off the fingers, resulting in zipper failure. Summary of the Invention

[0004] The purpose of this application is to provide a zipper pull and an article with chain teeth, which can solve problems such as the zipper pull easily slipping off.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: Firstly, embodiments of this application provide a zipper puller, including: a zipper puller body and a zipper tab; One end of the pull tab is rotatably connected to the pull head body, so that the pull tab can be switched between a flat and upright state relative to the pull head body; One end of the pull tab is provided with a partition, which abuts against the pull tab body when the pull tab is in the vertical position relative to the pull head body.

[0006] Secondly, embodiments of this application provide an article having chain teeth, the article comprising: a pair of chain teeth and the aforementioned zipper pull; The pull head is slidably disposed on the pair of chain teeth so that the pair of chain teeth can engage or disengage.

[0007] In this embodiment, the pull tab can rotate relative to the zipper head body, allowing it to switch between a folded and upright state. When the zipper head is not needed, the pull tab can be in a folded state; when it needs to be pulled, it can be in an upright state. Furthermore, a stop is provided at one end of the pull tab, allowing it to engage with the zipper head body when the pull tab is in the upright state. This prevents the pull tab from rotating, ensuring it will not continue to rotate under pulling force, thus facilitating the user's application of force. Compared to related technologies that require squeezing the pull tab with fingers to pull the zipper head, this embodiment eliminates the need for the user to squeeze the pull tab; simply flicking the pull tab is sufficient to pull the zipper head. This effectively alleviates the problem of the pull tab slipping from the user's fingers, ensuring smooth zipper operation. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0013] refer to Figures 1 to 8 This application discloses a zipper puller 01, which includes a zipper puller body 10 and a zipper tab 20.

[0014] The zipper head body 10 is a basic component that provides a mounting base for the zipper tab 20. In some embodiments, one end of the zipper tab 20 is rotatably connected to the zipper head body 10, so that the zipper tab 20 can be switched between a folded-down state and an upright state relative to the zipper head body 10.

[0015] It should be noted here that the "laid-down state" can be understood as the state of the pull tab 20 when the zipper pull 01 is in a stationary state or when it is pulled up. For example, the pull tab 20 extends towards the rear of the zipper pull 01. Figure 6 As shown; the vertical state can be understood as the state of the pull tab 20 when the zipper 01 is in the pulled-closed state, for example, the pull tab 20 extends upwards towards the zipper 01, as shown. Figure 8 As shown.

[0016] To ensure that the pull tab 20 can withstand the pulling force applied by the user when it is in an upright position, a partition 24 can be provided at one end of the pull tab 20. In this way, when the pull tab 20 is in an upright position relative to the pull head body 10, the partition 24 abuts against the pull head body 10.

[0017] Based on the above configuration, in this embodiment, the pull tab 20 can rotate relative to the pull head body 10, so that the pull tab 20 can switch between a folded state and an upright state. When the pull head 01 does not need to be pulled, the pull tab 20 can be in a folded state, and when the pull head 01 needs to be pulled, the pull tab 20 can be in an upright state. Furthermore, a partition 24 is provided at one end of the pull tab 20, so that when the pull tab 20 is in an upright state, the partition 24 can abut against the pull head body 10, thereby preventing the pull tab 20 from rotating and ensuring that the pull tab 20 will not continue to rotate when subjected to pulling force, thus making it easier for the user to apply force to the pull tab 20.

[0018] Compared to the method in related technologies where the user squeezes the pull tab 20 with their fingers to pull the zipper head 01, the embodiment of this application does not require the user to squeeze the pull tab 20 with force. Instead, the user only needs to flick the pull tab 20 to achieve the pulling effect on the zipper head 01. This can effectively alleviate the problem of the pull tab 20 slipping off the user's fingers and ensure that the zipper head 01 can be pulled smoothly.

[0019] refer to Figure 2 and Figure 4 In some embodiments, the zipper head body 10 may be provided with a groove 11 that extends through the front and rear direction of the zipper head body 10. Exemplarily, in practice, the pull tab 20 is provided in the top region of the zipper head body 10, such that the groove 11 can be formed in the top region of the pull tab 20 to facilitate the installation of the pull tab 20.

[0020] The groove 11 may include a bottom wall and two opposing side walls. The two side walls are spaced apart along the left and right directions of the pull head body 10, so that the two side walls and the bottom wall can together form an installation space.

[0021] At least a portion of one end of the pull tab 20 can be disposed in the groove 11 so as to accommodate at least a portion of one end of the pull tab 20 through the receiving space formed by the groove 11, thereby realizing the installation of the pull tab 20.

[0022] To achieve a rotatable connection between the pull tab 20 and the slider body 10, two side walls may each be provided with a connecting hole 112. One end of the pull tab 20 is provided with a connecting shaft 22, which is rotatably inserted into the two connecting holes 112, so that one end of the pull tab 20 is rotatably connected to the slider body 10. Figures 2 to 4 As shown. Based on this, the connecting shaft 22 is rotatably connected to the connecting holes 112 on the two side walls, which can ensure both the reliability of the connection between the pull tab 20 and the pull head body 10 and the smoothness of the rotation between the pull tab 20 and the pull head body 10.

[0023] Optionally, at least one of the slider body 10 and the slider tab 20 can be an elastic structure, so that the connecting shaft 22 can be passed through the two connecting holes 112 through elastic deformation. Of course, at least one side wall and the bottom wall can be connected by a detachable connection, so that when it is necessary to disassemble or assemble the slider tab 20, at least one side wall can be separated from the bottom wall to facilitate the engagement or disengagement of the connecting shaft 22 and the connecting holes 112.

[0024] refer to Figure 2 and Figure 4 In some embodiments, the bottom wall of the groove 11 may be provided with an arc-shaped groove 113, the two ends of which extend to two connecting holes 112 respectively, so that the arc-shaped groove 113 can connect the two connecting holes 112; a portion of the connecting shaft 22 is located in the arc-shaped groove 113. Based on this, the groove wall of the arc-shaped groove 113 can wrap around a portion of the outer wall of the connecting shaft 22, thereby further improving the smoothness of rotation between the connecting shaft 22 and the slider body 10. In addition, by providing the arc-shaped groove 113, a certain amount of space can be provided for a portion of the connecting shaft 22, which can help reduce the overall slider 01's vertical dimension (i.e., thickness).

[0025] In some embodiments, a partial area at one end of the pull tab 20 may protrude from the outer wall of the connecting shaft 22. When the pull tab 20 is in an upright state relative to the pull head body 10, the partial area at one end of the pull tab 20 may abut against the bottom wall.

[0026] Based on the above settings, when the pull tab 20 is rotated to the upright position, a portion of one end of the pull tab 20 will be obstructed by the bottom wall, preventing the pull tab 20 from continuing to rotate relative to the zipper head body 10. This ensures that the pull tab 20 can withstand the force applied by the user in the upright position without rotating, and thus the zipper head body 10 can be moved by the pull tab 20 to realize the pulling and closing process.

[0027] refer to Figure 3 and Figure 8 In some more specific embodiments, a partition 24 in a local area at one end of the pull tab 20 protrudes from the outer wall of the connecting shaft 22. When the pull tab 20 is in an upright position relative to the pull head body 10, the partition 24 abuts against the bottom wall. Based on this, the abutment between the partition 24 and the bottom wall can hinder the pull tab 20, preventing it from continuing to rotate after being rotated to the upright position, thereby enabling the pull tab 20 to withstand the pulling force applied by the user after being rotated to the upright position.

[0028] Optionally, the partition 24 can be a protruding structure, or other structures, which are not specifically limited here.

[0029] refer to Figure 3 and Figure 5 In some embodiments, the side of the pull tab 20 facing the bottom wall may be provided with a hook 23, which is used to engage with two adjacent chain teeth 02, thereby preventing the pull head 01 from moving and ensuring the stability of the pull head 01.

[0030] Considering that one end of the pull tab 20 is partially located in the groove 11 of the pull head body 10, in order to avoid interference between the hook 23 and the bottom wall of the groove 11, in this embodiment of the application, the bottom wall may be provided with a clearance hole 114. The clearance hole 114 can provide clearance space for the hook 23 so as to avoid the bottom wall blocking the hook 23.

[0031] The zipper head body 10 may be provided with a receiving space for accommodating the chain teeth 02, and the chain teeth 02 may also move in the receiving space during the pulling of the zipper head 01, so that the chain teeth 02 can engage or disengage during the movement of the zipper head 01.

[0032] The clearance hole 114 is connected to the receiving space. Thus, when the pull tab 20 is in a folded state relative to the pull head body 10, the hook 23 passes through the clearance hole 114 and extends into the receiving space to engage with two adjacent chain teeth 02 located in the receiving space along the front-back direction of the pull head 01. This ensures that the pull head 01 will not move back and forth when the hook 23 is engaged with two adjacent chain teeth 02, thus ensuring the stability of the pull head 01.

[0033] refer to Figure 3 In some embodiments, the hook 23 and the partition 24 can be respectively provided on opposite sides of the pull tab 20. Based on this arrangement, when the pull tab 20 is in the folded state, the hook 23 can be engaged in two adjacent chain teeth 02, while the partition 24 is separated from the bottom wall of the groove 11. When the pull tab 20 is in the upright state, the hook 23 is located outside the two adjacent chain teeth 02, while the partition 24 abuts against the bottom wall of the groove 11 to ensure that the pull tab 20 will not rotate after reaching the upright state, and to ensure that the pull tab 20 can withstand the force applied by the user in the upright state.

[0034] Optionally, the pull tab 20 can be a one-piece structure, that is, the entire pull tab 20 is manufactured by a one-piece molding method, such as casting, forging, or machining. This one-piece structure of the pull tab 20 can improve the overall strength of the pull tab 20, and can also shorten the manufacturing cycle and improve manufacturing efficiency.

[0035] For example, the pull tab 20 may have a through hole at one end away from the connecting shaft 22. This through hole can be used to thread a pull rope, reduce weight, reduce material usage, and lower costs.

[0036] In some embodiments, the zipper body 10 can be a single integrated structure.

[0037] Optionally, the zipper head body 10 may include a top plate, a bottom plate, a connecting post, a first side plate, and a second side plate. The top plate and the bottom plate are spaced apart in the vertical direction. The connecting post connects the top plate and the bottom plate and is located near the front end of the zipper head body 10. The first side plate and the second side plate are respectively disposed on the side of the bottom plate facing the top plate and are spaced apart in the horizontal direction. The first side plate and the second side plate are spaced apart from the top plate. In this way, the top plate, the bottom plate, the first side plate, the second side plate, and the connecting post can together form an accommodating space so that a pair of chain teeth 02 can be inserted into the accommodating space.

[0038] Furthermore, a groove 11 may be provided on the side of the top plate facing away from the bottom plate.

[0039] refer to Figures 2 to 4 In some embodiments, at least one sidewall of the groove 11 may be provided with a first limiting portion 111. Correspondingly, at least a portion of one end of the pull tab 20 may be provided in the groove 11, and the end face of the sidewall of the pull tab 20 facing the first limiting portion 111 provided in the groove 11 may be provided with a second limiting portion 21. When the pull tab 20 is in a folded state relative to the pull head body 10, the first limiting portion 111 and the second limiting portion 21 are mutually limiting.

[0040] Based on the above configuration, with at least a portion of one end of the pull tab 20 located in the groove 11, as the pull tab 20 rotates relative to the pull head body 10, the first limiting part 111 can engage with the second limiting part 21 to ensure that the pull tab 20 does not rotate arbitrarily when in the folded state. Of course, when the pull tab 20 is subjected to force, the force of the engagement between the first limiting part 111 and the second limiting part 21 can be overcome, allowing the first limiting part 111 and the second limiting part 21 to separate relative to each other, so that the pull tab 20 can rotate relative to the pull head body 10 from the folded state to the upright state.

[0041] By limiting the first limiting part 111 and the second limiting part 21, the pull tab 20 can be fixed in the folded state, which can effectively prevent the pull tab 20 from rotating freely relative to the pull head body 10 when the pull head 01 is not being pulled, causing the pull tab 20 and the pull head body 10 to collide and generate noise, or even damage to the pull tab 20 or the pull head body 10. Thus, it can improve the user experience and extend the service life of the pull head 01.

[0042] In some more specific embodiments, each of the two sidewalls may be provided with a first limiting part 111, and the first limiting parts 111 of the two sidewalls are arranged opposite to each other; correspondingly, the end faces of the pull tab 20 facing the two sidewalls may be provided with second limiting parts 21, and the two second limiting parts 21 are arranged opposite to each other. Based on this, when the pull tab 20 is in the folded state, the two second limiting parts 21 and the two first limiting parts 111 can be matched one-to-one to limit and cooperate, thereby increasing the limiting effect of the pull head body 10 on the pull tab 20, making it less likely for the pull tab 20 to rotate relative to the pull head body 10, and further ensuring the stability of the pull tab 20 in the folded state.

[0043] In some embodiments, one of the first limiting part 111 and the second limiting part 21 can be a limiting protrusion and the other can be a limiting groove. When the pull tab 20 is in a folded state relative to the pull head body 10, the limiting protrusion and the limiting groove are in a limiting engagement.

[0044] The first limiting part 111 can be a limiting protrusion, in which case the limiting protrusion can protrude into the groove 11; correspondingly, the second limiting part 21 can be a limiting groove, which is recessed from the end face of the pull tab 20 in a direction away from the side wall. Alternatively, the first limiting part 111 can be a limiting groove 11, in which case the limiting groove 11 can be recessed from the side wall in a direction away from the pull tab 20; correspondingly, the second limiting part 21 can be a limiting protrusion, which protrudes from the end face of the pull tab 20 in a direction close to the side wall.

[0045] Furthermore, the end of the limiting protrusion can be provided with an outwardly convex arc surface, and the limiting groove 11 can be provided with an inwardly concave arc surface, with the outwardly convex arc surface and the inwardly concave arc surface being adapted to each other. Based on this configuration, the contact area between the limiting protrusion and the limiting groove 11 can be increased, thereby improving the stability of the limiting fit, and effectively alleviating problems such as wear and scratches between the limiting protrusion and the limiting groove 11.

[0046] For example, both the convex and concave arc surfaces can be circular arc surfaces, elliptical arc surfaces, or spherical surfaces. Of course, they can also be irregular arc surfaces, etc. The specific type can be selected according to actual needs.

[0047] In some more specific embodiments, the first limiting part 111 can be a hemispherical structure, and the second limiting part 21 can be a hemispherical groove. In addition, there can be one or more first limiting structures located on one side wall, which can be selected according to actual needs.

[0048] Based on the aforementioned zipper pull 01, this application also discloses an article having chain teeth 02. The disclosed article includes a pair of chain teeth 02 and the aforementioned zipper pull 01. The zipper pull 01 is slidably disposed on the pair of chain teeth 02, so that the pair of chain teeth 02 can engage or disengage, such as... Figure 1As shown.

[0049] Optionally, items with chain teeth 02 can be clothing, flexible bags, zippers, etc., and of course, other types are also possible, without specific limitations here.

[0050] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
